emusonacid!

Apparently the bearings of the old 40x40x20 fan in my recently bought e6400 are worn out.
The noise is very irritating, but the replacement I had in stock, didn't help much either.
Probably too many rpms and/or way more cooling power, or whatever.

So now I plan to replace it with a new low noise Sharkoon fan (type S40).
My challenge however is that it has a displacement of only 5.9 ccm/hour, while the old one pushed away 8.8 ccm/hour.

Would that be too big of a difference in heat accumulation, you think?

Did you try replacing the fan in the end? I've just bought a 6400 classic and the psu fan is ridiculously loud.. defo need to do something about it

When replacing the fan check its data first before buying a new one.
The important parameter are the size of the fan, the type of power supply (12V) and the air flow rate (CFM).

i recently replaced the fan in my E4XT. this is the one i used, and i'm very happy with it, much quieter now:
